Download or read book Solidification Processing of Metal Matrix Composites written by Nikhil Gupta and published by Wiley-TMS. This book was released on 2006-11-10 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Solidification Processing of Metal Matrix Composites" (MMCs) focuses primarily on microcomposites but also covers macrocomposites, nanocomposites and foams. There are four main areas detailed: fundamentals of solidification synthesis, which examines issues related to stir mixing, pressure infiltration, transfer of particles or fibers through gas-liquid and liquid-solid interfaces, and particle/fiber interactions with fluids; processing and microstructures, which focuses on microstructure formation during solidification of MMC under different conditions, such as nucleation, growth, heat transfer, microsegregation, macrosegregation and interactions between solidifying interfaces, particles and fibers; and, properties of solidification processing, covering the relationship between the microstructures and properties. Comparisons are made between properties of solidification processed composites and monolithic and composites made by solid and vapor phase processes. It also details the application of solidification processed MMCs, revealing current and future applications especially in automotive, aerospace, railroad, thermal management, electromechanical machinery and recreational equipment sectors.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers several aspects of the synthesis of composites by the pressureless infiltration technique. It describes the methods used to obtain green preforms, such as cold pressed and hot sintering, describing the heating time, load, and time required for pressing the preforms. Additionally, wettability phenomena, which is directly related on infiltration, is extensively described. Wettability process and interfacial reactions are analyzed in many ceramic-metal systems prior to fabricate the composites. A complete description of fabrication processes for Metal Matrix Composites is included. An extensive section on structural, chemical, and mechanical characterization of composites fabricated with aluminum and magnesium alloys as matrices reinforced with titanium carbide (TiC), aluminum nitride (AlN), silicon carbide (SiC) and alumina (Al2O3) is included. Relevant techniques for joining composites, such as welding and brazing are addressed. As well as issues pertaining to the corrosion and wear of composites are discussed as well. Corrosion behavior of some composites exposed to aqueous media was analyzed. Corrosion of composites using TiC and SiC like reinforcement and Al, Ni, and some Al-Cux, Al-Mgx and Al-Cu-Li alloys like matrix is discussed extensively. The structural characterization techniques addressed include: scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), optical microscopy (OM), differential thermal analysis (DTA), high resolution transmission electron microscopy (HRTEM), and thermogravimetry analysis (TGA). Mechanical testing including hardness, elastic modulus, tension tests, and impact tests were used in the characterization of composites. Theoretical models for prediction of some mechanical properties are included too.

Available in PDF, EPUB and Kindle. Book excerpt: Semi-solid metal (SSM) processing, as a viable alternative manufacturing route to those of conventional casting and forging, has not yet been fully exploited despite nearly half a century since its introduction to the metal industry. The slow pace of adopting SSM routes may be due to various reasons, including capital costs, profit margins, and, most importantly, the lack of detailed analysis of various SSM processes in open literature to confidently establish their advantages over more conventional routes. Therefore, the SSM community must disseminate their findings more effectively to generate increased confidence in SSM processes in the eyes of our industrial leaders. As such, we have embarked on the task to invite the leaders in SSM research to share their findings in a Special Issue dedicated to semi-solid processing of metals and composites. SSM processing takes advantage of both forming and shaping characteristics usually employed for liquid and solid materials. In the absence of shear forces, the semi-solid metal has similar characteristics to solids, i.e., easily transferred and shaped; by applying a defined force, the viscosity is reduced and the material flows like a liquid. These unique dual characteristics have made SSM routes attractive alternatives to conventional casting on an industrial scale. With the intention of taking full advantage of SSM characteristics, it is crucial to understand SSM processing, including topics such as solidification and structural evolution, flow behavior through modelling and rheology, new processes and process control, alloy development, and properties in general. This Special Issue focuses on the recent research and findings in the field with the aim of filling the gap between industry and academia, and to shed light on some of the fundamentals of science and technology of semi-solid processing.

Available in PDF, EPUB and Kindle. Book excerpt: A detailed analysis of possible interfaces in cast aluminum silicon base reinforced particle composites containing SiC, Al2O3 and C indicates that several different kinds of interfaces can form. The reinforcements may be totally surrounded by primary-phase, or primary silicon, or by the eutectic between Al and Si. In addition, in some cases, some of the original coatings or their reaction products in the case of coated particles (like nickel or nickel-aluminum intermetallics in nickel coated reinforcements, Cu or Cu-aluminum intermetallics in Cu coated reinforcements) may also form the interface. The reaction between dispersoids and the alloy itself can form a complex interface. These different interfaces have also been experimentally observed in the microstructures of cast particulate composites, with the exception of primary a-aluminum surrounding the reinforcement. The absence of alpha-aluminum on the reinforcements is attributed to possible lack of nucleation, persistent lateral growth and a thermal lag between the reinforcement and the matrix. Estimates of works of adhesion for the different interfaces observed in cast composites have been made using the London Van der Waal equation, correlated to the properties of the composites, and used to identify the possibilities of further improving these properties.

Download or read book Diffusion Bonding 2 written by D.J. Stephenson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is currently great interest in the process of diffusion bonding. The main thrust has been in the joining of advanced materials such as superplastic alloys, metal matrix composites and ceramics and, most importantly, to introduce the process into mass-production operations. Diffusion bonding has also led to reduced manufacturing costs and weight savings in conventional materials and developments in hot isostatic pressing have allowed greater design flexibility. Since the first conference on Diffusion Bonding, held at Cranfield in 1987, considerable advances have been made and it was therefore considered appropriate to organise the Second International Conference on Diffusion Bonding which was held at Cranfield Institute of Technology on 28 and 29 March 1990. The meeting provided a forum for the presentation and discussion of recent developments in Diffusion Bonding and was divided into four main subject areas: steel bonding and quality control, diffusion bonding of aluminium alloys, bonding of high temperature materials and general applications. This structure is retained in the proceedings. DAVID STEPHENSON vii CONTENTS v Preface ......................... .
